The principal documents attributed to St. Patrick himself are his 'Confession,' the 'Epistles to Coroticus,' and a poem called the 'Lorica,' and sometimes the 'Deer's Cry.' Then we have in praise of Patrick a Hymn by his nephew, St. Sechnall or Secundinus, a metrical Life or Eulogy by St. Fiacc of Sletty, and certain sayings attributed to our national apostle in the _Book of Armagh_. We shall have also something to say of the _Tripartite Life of the Saint_, which is one of the earliest and most important documents connected with the history of the Patrician Church in Ireland. I.--ST. PATRICK'S CONFESSION. The _Confession_ of St. Patrick, as he himself calls it, or the _Book of St. Patrick the Bishop_, as it is called in the MSS., is the most important and interesting document connected with the primitive Church of Ireland. The text itself is found in the _Book of Armagh_, and in several ancient manuscripts, some of which belong to the tenth century.[87] It is referred to also in Tirechan's Collections in the _Book of Armagh_ as the 'Scriptio,' or Writing of St. Patrick himself. At the end of the copy in the _Book of Armagh_ it is described as the volume which Patrick wrote with his own hand--"Huc usque volumen quod Patricius manu conscripsit sua." This would seem to imply that the scribe of the _Book of Armagh_ took his copy from the autograph by St. Patrick himself. The evidence, both intrinsic and extrinsic, in favour of its authenticity is so strong that no competent Irish scholar has ventured to question the genuineness of this venerable document.
